Patented Jan. 13, 1953 KOREAN TYPEWRITER Pyung Woo Kong, Seoul, Korea Application July 8, 1949, Serial No. 103,570 In Korea May 18, 1948 2 Claims. 1

This inVehlzluIl relates to a typewriting machine for therewith writing in Korean language. Several machines for this purpose have been heretofore proposed and made, which are however deemed disadvantageous by those familiar with that language and its typewriting requirements, in that they were too complicated, unreliable in performance, too costly to manufacture, of high cost to the user, and impractical as well as unsatisfactory in the mode of presenting the written language. Various other serious objections are inherent in the said machines, as is well known to those familiar with the language and their uses and operations.

The principal object of the invention is to provide an improved Korean language typewriter, which will remedy all and other of the aforesaid disadvantages and objections, and be furthermore simplified, conveniently and economically manufacturable, salable at low cost, strong, rigid, durable, reliable, eflicient, conveniently utilizable, and capable of writing the language in a mode as required and acceptable by those familiar with it.

Another object is to provide an improved Korean language typewriter which will possess all of the aforesaid advantages of the invention, and utilize substantially all and identical parts, features, and operations of the conventional American machine, whereby the typewriter may be manufactured with ease, convenience, economy,

. and resort to the already existing facilities of the manufacturer of such machines, and hence resulting in low purchase price to the consumer.

Other objects and advantages will hereinafter appear;

In the accompanying drawings,

Fig. ,1 is a diagrammatic elevational view of a type writing machine embodying the invention.

Fig. 2 is a fragmentary diagrammatic plan view of the machine shown in Fig. 1.

Fig. 3 is a fragmentary plan view illustrating the focal guiding device of the invention.

Fig. 4 is a diagrammatic plan view illustrating the keyboard of the invention.

Fig. 5 shows a Korean language phrase as written on the machine of the invention.

Fig. 6 illustrates the Korean language writing symbols.

The type writing machine I, Figs. 1 and 2, cmbodies a series of bars 2 carrying types 3, each of said bars being pivoted at 4 and having in turn pivoted thereto at 5 a link 6 which is pivoted at I to a lever 8. Each of the levers 8 is pivoted at 9, carries a key II), and a spring I I normally draws the lever to an inoperative position and thereby maintains its link 6 and type bar 2 in the inoperative state shown. Striking on any key I0 transmits swinging motion to its type 3 about pivot 4, and causes the type to strike an impression upon a platen I2 mounted on a carriage I3 of the machine I. The machine I further embodies a lever plate I4 pivoted at I5, and a rod I6, pivoted to said plate at I1, passes through a plate I8, and carries at its terminal a head I9. Said plate I8 is pivoted at 20 and carries a pawl 2| which actuates mechanism 22 for advancing the carriage I3 in performance of the spacing function of the machine. 1

As seen in Fig. 4, the key board 23 of the machine comprises two clusters Illa, IOb of all keys Ill. When any key I0 belonging to cluster I0?) is struck its lever 3 strikes the plate I4, contrary to pressure of a spring 24, and causes it to actuate the mechanism 22, through movement of the rod I5, plate I8, and pawl 2|, for advancing the carriage I3 with the platen I2, upon impression of the type 3 with said platen. When however any key In belonging to cluster la is struck, the striking part But of its lever 8 enters a gap 25 in the lever plate I4, and thereby leaves said plate unactuated and the carriage I3 with the platen I2 stationary upon impression of its type 3 with the platen.

As shown in Fig. 6, the used symbols 26 for writing the Korean language comprise four

groups

27, 28, 29, 30, denominated pre-consonants, vowels, intermediate vowels, and sub-consonants respectively, the said groups including nineteen, fourteen, three, and twenty-seven symbols respectively, as illustrated. As seen in Fig. 5, the symbols 26 are used for composing characters, as 3|, 3la, 3Ib, 3|c, etc., any line or combination of such characters expressing a thought in the nature of a word, several words, a phrase, or sentence. For example, the illustrated characters in Fig. 5 are equivalent to the expression He has come. The said characters are generally separated by spaces 32, though at times two may be written without separation. In the forming of any character, as those herein shown, the first written symbol is in all cases a pre-consonant or belonging to the group 21, Fig. 6, and with said symbol is combined one, two, or three more symbols 26 belonging to the remainder groups 28, 29, 30. For example, considering the character 3|, Fig. 5, the first, written symbol 26a, is a preconsonant belonging to group 21, While the succeeding symbols 26b, 26c, 28d belong to the remaining groups 28, 29, 30.

In this machine, mg. 4, the keys in comprised in cluster 10a with their corresponding types 3, Fig. 1, carry the remainder of all symbols 2% belonging to the groups 28, 29, 30, while the keys comprised in cluster Hlb with their types carry the pre-consonants or the symbols 2% belonging to group 21, as well as Arabic numbers with English punctuations and signs as illustrated.

The type guiding device 33, Fig. 3, of the machine is. provided with two focal openings 34, 35, having the distance 36 between their centre lines 31 equal to the spacing distance of the platen l2. When any key H3 belonging to cluster i617, Fig. 4, is struck, its type 3 is guided for impression upon the platen I2 by the opening 35, while the striking of any key belonging to the cluster Illa guides its type to the platen through the opening 34, the operation of the key of cluster lflb causing a space movement of the carriage l3 and platen l2, while striking the key of cluster ma does not afiect the carriage and platen, which thus remain stationary.

When it is desired to write any character, as 31, Fig. 5, the key liic of cluster 19?) is first struck, which causes the type of the pre-consonant 26a to be guided through the opening 35 for impression on the platen area opposite thereto and moves the platen i2 one space to bring said area into registry with the focal opening 36. The typist then strikes successively the keys ltd, Hie, 19f of cluster iiia, which operations cause the types of the remainer symbols 2612, 2%, 26d to strike the platen i2 through the focal opening 34 and write the said symbols in their appropriate relation shown in Fig. 5, while the platen remains stationary. The space bar 33, Fig. 2, may be then struck for normal advancement of the carriage, for creating the space 32, and the numbers, punctuations, and signs seen in Fig. 4 may be written on this machine by striking their keys in conventional manner.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:
